What Is a Slow Cooker Potato and Onion Bake?
This recipe is a slow-cooked potato casserole made by layering thinly sliced potatoes with onions, a creamy seasoned sauce, and shredded cheese.
Unlike oven-baked potato casseroles that require constant attention, the slow cooker gently cooks everything over several hours, resulting in perfectly tender potatoes infused with rich flavor.
It's similar to scalloped potatoes but even easier because the slow cooker handles the cooking for you.
